Copper(I) iodide is the inorganic compound with the formula CuI. It is also known as cuprous iodide. It is useful in a variety of applications ranging from organic synthesis to cloud seeding.uI has several uses: 1  CuI is used as a reagent in organic synthesis. 2  In combination with 1,2- or 1,3 diamine ligands, CuI catalyzes the conversion of aryl, heteroaryl, and vinyl bromides into the corresponding iodides. 3  NaI is the typical iodide source and dioxane is a typical solvent (see aromatic Finkelstein reaction).
